Background

HBsAg is the surface antigen of the hepatitis B virus (HBV). It indicates current hepatitis B infection. Today, these antigen-proteins can be a genetically manufactured (e.g. transgene E. coli) to produce material for a simple antigen test, which detects the presence of HBV. In histopathology, the presence of HBsAg is more commonly demonstrated by the use of the Shikata orcein technique, which uses a natural dye to bind to the antigen in infected liver cells.
